Be i known that we JonN G. REISER and JACOB W. HUBBELL, citizens ofthe United States, and residents of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Agglutinator; and we do hereby declare the following to be a full, clear, and exact description lof the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon,

which form a part of this specification.

Our invention relates to a means for spreading agglutinants' and other materials material and keeping it in a uniform degree of plasticity or liquefaction and one which is not destroyed in the use thereof and is 'refillable and one having a means for spreading the material in its application to objects. and one wherein the parts may be easily dis connected for cleaning or refilling I By our invention is provided ameans wherein the adhesive material is pneumatically ejected from a container. A means is provided for producing a pneumatic pressure within the container. Also a means is provided for permitting the exit of the connecting agent from the container as it is used. A' suitable spreading device is also provided at the point of ejectment of the glue for spreading the cementing or sealing material.

The construction selected is illustrated in the accompanying drawings.

In the drawings, Figure 1 illustrates a top view of a device embodying our invention.

on Fig. 2. Figs. 4 and 5 illustrate spreaders or nozzles for spreading the material.

1 is acontainer for agglutinating material which may be made in any suitable form such as cylindrical. Airmay be forced into one part of the container above the surface of the agglutinating'material and an exit is provided at another part of the container for allowing the agglutinatmg material to escape.

A valve 2 located in a shell 3 is placed at one end of the cylinder 1. The cylinder 1 l and the shell 3 are screw threaded whereby they may be tightly sealed together. The valve 2 is provided with a stem 5 which extends centrally with respect to the shell 3. A centering star 6 is located on the one end of the stem 5 and a spring 7 i located between the end wall of the shell 3 and the star 6. 'A pin 8 or other suitable device is inserted through the end of the stem 5 for holding the spring 7 in compression on the stem 5. The spring 7 operates to hold the valve 2 seated in an opening in the .end wall of the shell 3.

A connection may be made with the shell 3 for forcing air or other suitable gas through the valve 2 into the container 1. pump 10 may be connected to the shell 3 to hold the container and pum in alinement. They are cylindrical and orm a convenient handle for the manipulation of the instrument. The pump 10 is preferably of the same size and shape as the container 1 and is secured to the shell 3 by means of threaded portions of the shell and the pump cylinder. A piston 11 is located within the pump cylinder 12 and consists of a cup washer 13 which is located between the two metal washers 14 and 15. The metal washer 14: being substantially ofthe same diameter as the interior of the pump cylinder 12 while the washer 15 is substantially the same diameter as the washer 14 less double the thickness of the cup washer 13. The piston 11 may be secured to the stem 16 by means of a screw 17. The piston rod 16 moves through a threaded cap plug 19 and is secured to the handle or knob 20 which is threaded to the outer end of the rod 16.

In order that the pump 10 may be easily removed and taken apart, a gnarled flange 24 located on the shell 3, is provided. It has holes 25 which afford means in addition to the gnarled flange for gripping the shell 3.-

A spanner wrench or a pointed instrument of suitable shape may be inserted in the holes to turn the shell. The stem 16 is provided with a hole 26 near the handle 20. A pointed instrument may be inserted in the hole 26 and the handle 20 may be turned so as to unscrew the handle from the stem 16 or to tightly screw the handle to the stem 16. The hole 26 affords a means for holding the stem 16 to prevent turning when the handle is screwed or unscrewed. When the handle is removed from the stem 16, and the cylinder 27 located just beyond the piston when the piston is in its outermost position. The openings 27 form ports which allow the air to pass into the cylinder ahead of the piston each timethe piston is drawn to the end of the pump prior to each compression stroke.

The air rushes in through the openin s 27 a and fills the pump cylinder at at-mosp eric pressure in front of the piston which, u on its compression stroke, empties the cylin ers of the air and force it through the valve 2 into the container 1 and above the surface of the agglutinating material contained therein.

The end of the container is provided with a plug 30 having a gnarled flange 31. The block 30 is provlded with a screw threaded opening 32 in which a threaded tube 33 is secured. A ring 34 is also secured by the plug 30 inposition between the flange 31 and the end of the container 1. The ring 34 is provided with an ear 35. A tube 36 is secured in an opening in the car 35 and is soldered sweated or otherwise secured to the end of the tube 33. It extends. diagonally from the edge of the container to the end of the tube across theend of the container. The lower end of the tube 36 is provided with an opening 37 which is located within the area of the outer end of the tube 33 and affords a passageway connecting the interior of the two tubes. The'tube 36 is provided with a cone shaped needle valve 40 which seats itself on an inner tube 41 having a small bore forming a valve seat at a point just below the opening 37. When the valve 40 is opened, the adhesive material is forced by the pneumatic pressure on its surface through the tube 33 and opening 37 and provided with ears 44 which are located on opposite sides of the stem 43 and between two collars or flange 45. The ears v44 are preferably made circular in shape and operate upon the collar 45 to raise or lower the stem 43 and to open and close the valve 40. The lever 42 is pivoted to a ring band 46 which is provided with ears 47 that may be clamped together by: means of a bolt 49 which also forms a pivot for the lever 42. The end of the lever arm is provided with a bolt 50 having a broad flat head 51 which forms a finger piece for operating the 'lever 42. The lever 42 is provided with a threaded ring 52 into which the screw 50 may be adjustably secured. A spring 53 is located between the end of the lever 42 and the surface of the container 1 and held in position by the screw 50.' The finger piece may be screwed into the ring 52 more or less to regulate the extent of movement, of the handle and valve 40. If it is desired to allowa very little of the adhesive material to escape through the bore in the block or tube 41, the finger piece 51 may be turned so as to bring the end of the nut 50 close to the surface of the container 1 and thereby prevent extended movement of the lever 42. If it is desired to open the valve 40 to a greater extent, the bolt 50 is unscrewed so as to form a greater inte'rvening space between to the axis of the spreader block 60 and of the tube 36 in order that the agglutinator may be conveniently inclined while in operation and so as to bring the surface 62 in the plane of the surface which is being operated upon, the connections of the tubes are such as to bringthe block near one of the lines of the cylinders which conveniently positions it for the manipulation of the tool. The surface 62 may be flat, curved or any suitable shape or size according to the character of work that is done. The spreader may be easily replaced by unscrewing the spreader block or nozzle from the end of the tube 36 and screwing on another spreader of suitable shape and size as may be desired and according to the char-- I of spreaders of different sizes. The spreaders may be provided with flanges of differ- .connected cylinders, one of the cylinders ent widths like that shown in Fig. 5. The flange 7 0 provides anextension of the elliptioal surface forming the spreading or contact surface of the agglutinator. The agglutinating material is forced through the opening 61 in between spreading surface and the surface of the object to which the adhesive material is to be applied. The spreading surface conforming to and being placed in close contact with the object to be coated, the air forces the adhesive material into the crack or thin space between them. It is spread outwardly or laterally from the hole 61 by the pressure and spreading surface into a very thin intervening layer so that by merely bringing the spreading surface of the instrument into close contact with the surface of the object to be coated, the adhesive material is rapidly spread as the instrument is moved over the surface of the object.

The material being under pressure and the outlet of the'material being closed by the valve 40, the tendency of the air pressure is to force the material up around the valve stem 43 and if it should dry in this position, it would lock the valve stem 43 and prevent operation of the valve 40, except for the fact that a packing material 71 is located around a reduced portion of the valve stem 43 in the tube 36. The packing must contain a material-which will preyentrthe agglutinating agent from passing up the stem where it will dry and prevent movement of the valve thereto. The packing is preferably formed of tallow or soap or other material containing grease or .oil. The packing, however, is of such a nature that it will retain its form notwithstanding the ordinary temperatures to which the instrument may be subject. 7

The construction selected and described may be greatly varied in the arrangement and manufacture of its parts and in the substitution of elements having equivalent functions. and such modifications may be used for many varied purposes and still contain the invention which is described in.
